Research direction
Examine the source code in typeahead.js to find where the NotFound template is displayed during remote requests. Look for the event handler for keypress or query change that triggers the remote call. The issue is that the NotFound template is shown before the response arrives, causing a flash. The fix may involve delaying the display of the NotFound template until after the remote request times out or fails.
